Title: A new dental instrument primarily for the massage of the gums by the patient himself
IPC: A61H13/00
Filed: 1951-10-22
Abstract: 714,771. Massage appliances; teeth cleaning appliances. HIRSCHTRITT, E. Jan. 22, 1953, [Oct. 22, 1951], No. 24610/51. Class 81(2) An instrument for massaging or cleaning interdental spaces comprises a probe borne by a carrier element the axis of which is perpendicular to the probe and is adapted to fit on a finger, so that the axis of the probe is perpendicular to the finger. The probe 1 is of sector-shaped cross-section the broader longitudinal massaging edge being transversely rounded. The carrier element is in the form of a C-clip 6 of rectangular or arcuate cross-section. The C-clip 6 is made of synthetic resin e.g. polyvinyl, polystyrene or methyl methacrylate resin and is integral with or secured e.g. by screwing, to the probe 1 which is of the same material, hardwood or metal. A cover may be provided for the probe 1. The carrier element may alternatively be in the form of a band or thimble.

Title: A System for Maintaining Output Frequency of a Motor-driven Current Source Substantially Constant
Inventor: SMITH PETER
IPC: H02J9/08
Filed: 1967-05-26
Abstract: 1,183,040. Standby power supply systems. DYNAMICS CORP. OF AMERICA. 26 May, 1967, No. 24625/67. Heading H2H. [Also in Division G3] A standby power supply system comprises a generator supplying a load, the generator normally being driven by an electric motor connected to an electric power supply and, upon failure of the electric power supply, by a prime mover which is started up when the failure occurs, the drive for the generator during the starting up period being maintained by a fluid pressure motor such as an hydraulic motor, the hydraulic motor also serving as a means for maintaining constant an output parameter of the generator. The system comprises a fluid pressure accumulator connected to a pipe line 43 and a device 71 producing a signal dependent upon the output frequency of the generator 15. The signal is fed to a differential amplifier 99 together with an adjustable frequency reference signal 103, the amplifier output being connected to relays 115, 123 which operate a fluid distributing valve 35 to connect the hydraulic motor 25 to the fluid pressure accumulator or by way of a restrictor valve 34 to a fluid reservoir 27. Thus the hydraulic motor 25 will tend to increase or decrease the generator speed to correct any frequency error. Should the electrical power supply fail a power monitor 81 causes a standby prime mover 17 to start up and at the same time causes the fluid distributing valve 35 to connect the hydraulic motor 25 to the pressure accumulator thereby maintaining the generator drive. A tachogenerator 65, driven by the standby prime mover 17 provides a signal 69 dependent upon the prime mover speed and is fed, together with the generator frequency dependent signal 101 to a second differential amplifier 107. When the two signals are in synchronism the amplifier output causes energization of a clutch 19 whereupon the generator 15 is driven by the standby prime mover 17. A comparator 109 supplied with signals 82, 101 dependent upon the electrical power supply and the generator frequency is effective to ensure that the standby prime mover 17 drives the generator 15 until the electrical power supply returns to normal.

Title: Magnetic field measuring apparatus
IPC: G01V3/15
Filed: 1957-08-13
Abstract: 861,927. Magnetic tests. VARIANASSOCIATES. Aug. 13, 1957 [Aug. 14, 1956], No. 25580/57. Class 37. The intensity of a magnetic field is measured by apparatus which produces successive polarizations of gyromagnetic bodies in the field allowing free precession between the polarizations, derives a signal whose frequency is dependent on field intensity, mixes the signal with a fixed signal to derive a further variablefrequency signal and measures the frequency of the third signal. As shown, the gyromagnetic dilutor 1, comprising a coil of wire wound round a sample of water, forms the inductive portion of a tuned circuit, of which the capacitive portion is formed by a bank of capacitors 2 selectively coupled by a switch 3. A programmer 7 which may be merely a switch or a multivibrator operates a polarize-receive relay 4 which first connects a battery 5 to the coil to produce a polarizing magnetic field and then disconnects the battery to allow free precession of the gyromagnetic bodies. The same coil as is used for polarizing the sample is used to detect the precession and applies an output through a narrow band filter 8 tuned in step with the coil 8 by condenser bank 9 and switch 11 to a mixer circuit 12 where it is heterodyned with the output of a load oscillator 13 tunable in coarse steps by condensers 14 and inductances 16 and in fine steps by condensers 18. The lower sideband of the mixed output is selected by a filter 21 and its frequency is either indicated directly on a vibrating reed meter 28 or it is frequency multiplied at 22 and heterodyned with the output of a fixed oscillator 28 at mixer 24, the lower sideband selected at 27 and again frequency indicated on vibrating reed frequency meter 28. A calibration oscillator 32 is provided. In a simplified arrangement (Fig. 3, not shown) the output of the narrow band filter is frequency multiplied and combined with a local oscillator. The lower pass-band is then selected and its frequency indicated directly. In an arrangement for indicating magnetic gradient (Fig. 4, not shown), the arrangement of Fig. 2 is effectively doubled using a common battery, programmer, local oscillator, fixed oscillator and frequency indicator. The two samples are spaced by a known amount and the frequency meter which is of the vibrating reed type gives two readings. A knowledge of the field gradient may be determined by subtracting these readings.
